- Andy has 4 apples, and then eats 2. How many does he have left?
- Beth drives for 3 hours at 80 km/h. How far did she go?
- Carl, Debbie and Earl earned $30 together shoveling driveways. How much does each of them get?
Is there a name for this sort of 'simplest possible' word problem?
Is there any well-defined classification or hierarchy of such problems?
For example, the third on my list requires the pre-processing step of recognizing group of three entrepreneurs before doing the division, which adds a degree of difficulty.
It seems to me that such a classification system might be pedagogically useful, but I don't know whether one exists or is widely accepted.
